FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which chassis accepts the AT-PWR4?
The AT-PWR4 is designed for the Allied Telesis AT-MCR12 Media Conversion Rack-Mount Chassis.
Can the AT-PWR4 be installed as an auxiliary supply?
Yes. The installation guide documents installation in the AT-MCR12 auxiliary power-supply slot.
Can the AT-PWR4 be hot-swapped?
Yes. A failed supply can be replaced while the other AT-PWR4 continues powering the chassis.
What should be verified before connecting Allied Telesis AT-PWR4 to AC mains?
Confirm that the site supply matches either 100–120 VAC at 3.0 A or 220–240 VAC at 1.5 A, both at 50/60 Hz. Use the correct grounded power cord and connect the AT-MCR12 chassis to a properly wired protective-earth outlet before energizing it.
What does the AT-PWR4 POWER LED indicate?
Green indicates normal operation; an unlit LED indicates that the supply is off or has failed.
What should be checked if Allied Telesis AT-PWR4 overheats or a chassis fan does not run?
Keep all ventilation openings clear, verify that ambient temperature does not exceed 40 °C, and confirm that both supplies are fully seated and powered. If a fan remains stopped after these checks, the installation guide treats power-supply failure as likely.
How should an AT-PWR4 installation be grounded?
The chassis must be connected to a properly wired, earthed socket through the specified grounded power connection.
